Description
Folate Receptor Antibody Test Cost, Process, and What’s Included
The FRAT® test checks for blocking and binding antibodies to the folate receptor-alpha. These antibodies may interfere with folate transport into the brain and are often considered in autism, developmental delay, language delay, and suspected cerebral folate deficiency.
This package includes the FRAT® test kit, lab processing, physician consultation, questionnaire review, and a written report from David Epstein, D.O.
```What You Get
```FRAT® Test Kit and Lab Processing
The FRATNow collection kit is shipped to you. Blood is drawn locally by a phlebotomist, nurse, or approved draw site, following the FRATNow collection and shipping instructions.
Comprehensive Questionnaire
The questionnaire reviews autism-related concerns, developmental history, language and social communication, folate sensitivity, nutrient concerns, gut/immune patterns, and methylation-related traits.
Physician Interpretation and Report
David Epstein, D.O. reviews the FRAT® result, questionnaire, and relevant history, then provides a written report with practical next steps.
Leucovorin When Appropriate
When the FRAT® test is positive and the clinical history supports treatment, leucovorin / folinic acid may be prescribed.
Why the Questionnaire Matters
The FRAT® result is important, but it is only one part of the decision. The questionnaire helps place the test result into a broader clinical context.
```If FRAT® Is Positive
The report helps determine whether leucovorin / folinic acid is clinically appropriate, what concerns should be considered, and what follow-up may be needed.
If FRAT® Is Negative
A negative test can still be useful. The updated questionnaire can help identify other nutrient, methylation, gut, immune, inflammatory, or functional health patterns that may deserve follow-up.

Who Should Consider FRAT® Testing?
Autism and Development
- Autism spectrum concerns
- Language delay or regression
- Social communication concerns
- Developmental delay
Folate Transport Concerns
- Suspected cerebral folate deficiency
- Prior concern for folate receptor antibodies
- Interest in leucovorin / folinic acid treatment when clinically appropriate
- Neurologic or behavioral symptoms where folate transport problems are being considered
When FRAT® Is Positive vs. Negative
```If FRAT® Is Positive
The main concern is impaired folate transport related to folate receptor antibodies. In this setting, leucovorin / folinic acid may help bypass the folate transport issue.
Your report explains the result, clinical significance, treatment considerations, and follow-up recommendations.
If FRAT® Is Negative
A negative result may suggest that folate receptor antibodies are not the main driver, but symptoms may still involve other biochemical or functional patterns.
- Undermethylation or high histamine patterns
- Low SAM or elevated SAH
- Zinc deficiency or copper imbalance
- Gut and immune burden
- Inflammation, glutathione demand, or mitochondrial stress
What Is Included in the $594 Package?
- FRAT® test kit and lab processing: $295
- Physician consultation and written report: $299
- Symptom and history questionnaire review
- FRAT® result interpretation
- Discussion of leucovorin / folinic acid when clinically appropriate
- Next-step recommendations when FRAT® is negative or incomplete
- Guidance on whether broader methylation or nutrient testing may be useful
Why Physician Review Matters
Many patients and parents search for the FRAT test cost because they want the lab test itself. The lab result is important, but it is only part of the decision.
A positive FRAT® result may raise the question of leucovorin treatment. A negative result may shift attention toward methylation, nutrient status, gut/immune factors, inflammation, or other contributors.
The physician review helps connect the test result to the patient’s actual symptoms, history, and next steps.

Clinical Evidence: One landmark study by Frye et al. (Molecular Psychiatry, 2016) found that children with autism and language impairment who were positive for folate receptor autoantibodies showed significantly improved verbal communication after 12 weeks of high-dose folinic acid therapy. Those who were FRAA-positive had even greater benefit, with a large effect size (Cohen's d = 0.91).
